Just decided I need to get a pair of X metals. Problem is, I am having trouble figuring out were to start. Do any of the Oakley stores in Las Vegas have X metals to try on to decide which ones to get? Should I just start with Juliets or should I consider something else? Is ebay the go to place to get them?

Stores first but time is not on your side. Check out the X metal exchange forum here, Ebay (careful there, educate yourself and know what your looking at before you buy from Ebay especially), Oakley Vault stores maybe. As far as which pair to get, If you have a large head, Romeo 1, Romeo 2, X Squared, and some say XX are good, if you have a smaller head Juliets, Penny, and maybe Half X..not sure of the fit for the half X. Easier pairs to obtain seem to be Juliets and X Squared from what I have seen.
